APPARATUS FOR UTlLIZING THE WASTE HEAT OF GAS-ENGINES.

SPEGI I ICA'JTIQN forming pair' t of Letters Patent No. 290,451, dated December 18, 1883.

Be it known that I, J. VAUGHAN Mnnmcic, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Apparatus for Utilizing the Waste Heat of Gas-Engines, of which the following is a specification.

My invention relates to that class of gas-engines in which the cylinder is maintained in a comparatively cool condition by water, caused to circulate within a jacket by which the said cylinder'is surrounded; and my invention consists in so combining the cylinder and its jacket with warming apparatus and with connecting-pipes, that the water, which has become heated by circulating in contact with the cylinder, shall be made the medium of warming an apartment before it returns to the j acket in a comparatively cool condition.

1n the accompanying drawing, which illustrates one mode of carrying myihi ention into effect, the cylinder A only of tlicsgas-engine is shown. f i

The warming apparatus G consists, in the present instance, of the well-known system of zigzag heating-pipes; but any structures for radiating into an apartment heat derived from hot water or steam circulating through the structure may be used in place of the pipes G.

A pipe, D, forms a communication between the jacket at the top of the cylinder and the alien filed June 18, 1883.

uppermost of the series of pipes G, the lowest (N0 model.)

being in communication, through a pipe, E, with the jacket at the under side of the cylinder. The water which has been heated by circulating within the jacket in contact with the cylinder passes upward through the pipe D to the top of the heating apparatus, while water which has been cooled in passing downward through the system of pipes enters the jacket through the pipe E. Thus a constant circulation of water is maintained through the jacket and through the heating apparatus and connecting-pipes, the heat derived by the water'froni the cylinder being radiated into an apartment, and, after losing much of its heat in performing this duty, the water returns to the jacket of the cylinder, to perform the additional duty of maintaining the said cylinder in a comparatively cool condition.

I claim as my invention The combination of the cylinder and waterjacket of a gas-engine with heating apparatus and connecting-pipes, by which water is caused to circulate through the jacket and through the heating apparatus, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

J. VAUGHAN MERRICK.
